An electromagnetic device can gently sort cells by levitating them to different heights. It looks like a magic trick: cells at the bottom of a liquid medium begin levitating, then hovering at a ...

Poly(N-isopropylacrylamide) (PNIPAM) hydrogel undergoes significant but precise changes in size between 20°C and 40°C, making it an excellent candidate for use in variable-size deterministic lateral ...

Stanford Medicine researchers invent an electromagnetic device that can gently sort different types of cells by levitating them to different heights. It looks like a magic trick: Cells at the bottom ...

It looks like a magic trick: Cells at the bottom of a liquid medium begin levitating, then hovering at a particular height. With no physical contact, an invisible force directs certain cells to float ...

Around the same time, Mack Fulwyler, an engineer working at Los Alamos National Laboratory, needed to separate particles, so he drew on existing techniques to create droplets to separate cells from a ...

Using an array of poly(N-isopropylacrylamide) (PNIPAM) micropillars whose size varies precisely with temperature, this device can be precisely tuned to sort cells across a range of sizes.
